Delays on Macmini

Not sure if I have a MacMini problem, issue with the latest version of Audirvana, or OS X 10.13.1. Last two change were both made and this problem started cropping up.

I’m seeing delays pulling up album songs or advancing songs in the A+ remote. The dialog opens but doesn’t fill-- just spins waiting for content. At the same time my MacMini remote cannot advance songs either (indicating its not a problem with A+). Things will often catch up and it resumes. If I remotely screen into the MacMini, everything immediately recovers. I see an Audirvana notification dialog quickly slide to the right about notifications (but never get to read the whole thing). Seems to occur with local content and Tidal.

BTW, love the MQA icon indication for Tidal songs!
